How to Make It
Combine first 3 ingredients in a large bowl; add chicken to bowl, and toss to coat. Let stand 15 minutes, turning chicken occasionally.
Remove chicken from bag, reserving marinade. Place marinade in a small saucepan; bring to a boil. Cook until reduced to 1/4 cup (about 5 minutes). Thread chicken and bell peppers on 8 (12-inch) wooden skewers. Brush skewers with marinade. Place skewers on grill rack coated with cooking spray. Grill 4 minutes on each side or until done, brushing occasionally with remaining marinade. Remove from grill; sprinkle with sesame seeds. Serve with rice.
